<p>FakeMotion script running</p>
<p>horizontal beam position 1.0 mm (new beam target overlap)</p>
<p>vertical beam position -5mm</p>
<p>Beam intensity 7.0e+7 particles.</p>
<p>Target density ~4e11 at/cm2</p>
<p>Target temperature is 36.6 K. Values of E1 is 820 Hz, 2.6A, 1.4e-1 mbar</p>

<p>No difference observed between bunched and coasting</p>
<p>See attached screenshots to compare to previous run</p>
<p>Saw an increase in the data rate to disk ~ 2000 kB/s. On spectrum browser we saw aida15 had HEC reading hot. ASIC check on aida 15 resolved issue</p>
